Replacing Factory Gauges??
The Factory Gauges dash was different than the standard
dash. These Adaptors allow the use of SHIFTWORKS ®
Gauges series #S505 to be used in the factory original gauges dash.
Our gauges were designed to fit the standard dash, and these adaptors
were made in response to requests from customers.

Neck with sending unit holes.
#S533 . . . $48.50
The Temperature Sending unit should be located in the intake
manifold near the thermostat. Some newer engines have sending
unit locations that are inconvenient. This GM Water Neck can
solve that problem.
#S534 . . . $20.00
Use this Shiftworks unit if your engine requires a sending
unit smaller than the ½ inch pipe thread-sized unit
supplied. Our sending unit is 1/8
inch NPT and comes with a 1/2 inch NPT adaptor. A 3/8 inch
NPT adaptor is available on request.
